摘要：
A toner for full-color development for use in a developing system of a full-color image forming apparatus which comprises a binder resin having a glass transition point Tg of from 60.degree. to 75.degree. C., a number-average molecular weight Mn of from 3500 to 6000, a ratio of a weight-average molecular weight Mw to the number-average molecular weight Mn (Mw/Mn) ranging from 3 to 8, and a difference between a temperature T.sub.1 at the apparent melt viscosity of 1.times.10.sup.5 poise and a temperature T.sub.2 at the apparent melt viscosity of 1.times.10.sup.6 poise DT (=T.sub.1 -t.sub.2) in the range of from 8.degree. to 15.degree. C.
